Answer:

Step-by-step explanation:

hope it helps ya ....

It is assumed that the efficiency of men is higher by the factor 15/12 than that of women.) The question :How many days would be needed by 6 men and 10 women can be reduced to the question How many days would be needed by 6 + 10x(12/15) = 6+8 = 14 men, if the same work can be done in 21 days by 12 men?

The answer is

X = 21x(12/14) = 18 days.

Answer 2

Answer:

18 days

Step-by-step explanation:

12 men or 15 women can complete a work=21 days

6 men and 10 women can complete in how many days.

We solve this question by short trick-

=12*15*21

=12*10=120

=15*6=90

=120+90

=210

so by this logic-

= 12*15*21/210

=12*15/10

=12*3/2

=6*3

=18 days
